Problems solved by technology

Oxygenates make the fuel less energy dense and like NMA, they must be added at high treat rates, potentially causing compatibility issues with fuel storage, fuel lines, seals and other engine components

Embodiment approach

[0049] According to a preferred embodiment, the one or more aromatic hydrocarbons are selected from those comprising the following on the benzene ring: a single substituent; or two substituents at the meta or para position; or at the meta position three substituents.

[0050] The one or more aromatic hydrocarbons are more preferably selected from toluene, ethylbenzene, xylene (and especially 1,2-dimethylbenzene or o-xylene, 1,3-dimethylbenzene or m-xylene -xylene and 1,4-dimethylbenzene or p-xylene, preferably m-xylene and p-xylene), 1-ethyl-3-methylbenzene, pod (1,3,5- trimethylbenzene), 1-ethyl-3,5-dimethylbenzene, and mixtures of these compounds.

[0051] Particular preference is given to toluene, xylene and mixtures of these compounds.

[0052] Furthermore, the composition according to the invention has a weight ratio of its amount of cyclopentane to its amount of aromatic hydrocarbons greater than or equal to 2. Preferably, the weight ratio lies in the range 2 to 7, mo...

Embodiment 1

[0082] Example 1 : preparation of the composition according to the invention

[0083] Composition C according to the invention was prepared from the following starting compounds (compounds) A and B:

[0084] -A: a mixture of 75.5% by weight of cyclopentane and 24.5% by weight of aromatic hydrocarbons formed from a mixture of toluene and xylene, having the composition detailed below:

[0085] Composition of Mixture A %weight Cyclopentane 75.5 Toluene 6.8 p-xylene 6.3 O-xylene 2.8 m-xylene 6.6 Ethylbenzene 2

[0086] -B: isooctane (2,2,4-trimethylpentane).

[0087] Composition C is obtained by simply mixing 50% by weight of A with 50% by weight of B. Its final composition is as follows:

[0088] - 37.75% by weight cyclopentane,

[0089] - 12.25% by weight aromatic hydrocarbons,

[0090] -50% by weight isooctane,

[0091] - cyclopentane amount / aromatic hydrocarbon amount weight ratio = 3.1.

Embodiment 2

[0092] Example 2: Properties of Fuel Composition C

[0093] The following parameters were measured for composition C according to the invention and for each of the starting compounds (compounds) A and B:

[0094] Octane number RON , according to the protocol described in standard ASTM D 2699-86:

[0095] -RON(A)=102.7

[0096] -RON(B)=100

[0097] -RON(C)=104.9

[0098] It is clear that:

[0099] RON(C)>RON(A),

[0100] RON(C)>RON(B), and

[0101] RON(C)>(RON(A)+RON(B)) / 2

Abstract

The present invention relates to a fuel composition comprising: from 35% to 75% by weight of cyclopentane, from 10% to 25% by weight of one or more aromatic hydrocarbon(s), and up to 55% by weight ofone or more branched alkane(s) chosen from 2-methylbutane and trimethylpentanes, with a weight ratio of the cyclopentane content to the aromatic hydrocarbon content greater than or equal to 2. The invention also relates to the use of such a composition for supplying a spark ignition engine, in particular for increasing the engine power and / or for reducing the specific fuel consumption of the engine and / or for increasing the octane number (RON).

Description

technical field [0001] The present invention relates to a fuel composition intended for use in vehicles comprising spark ignition engines (also known as gasoline engines) having an increased level of performance both in terms of engine power and energy saving. [0002] The invention further relates to the use of such compositions in spark ignition engines for increasing power and / or reducing specific fuel consumption. Background technique [0003] Gasoline-type fuels that can be used in spark-ignition engines, especially those in motor vehicles, must have a sufficiently high octane rating to avoid knocking problems. [0004] It is well known that the octane number measures the resistance of fuels used in spark ignition engines to self-ignition. [0005] Typically gasoline fuels sold in Europe complying with standard EN 228 have a Motor Octane Number (MON) of greater than 85 and a Research Octane Number (RON) of at least 95. These fuels are suitable for most motor vehicle e...
